Display: List known vectors and types
General Form:
display [varname ...]
Prints a summary of currently defined vectors, or of the names specified. The vectors are sorted by name unless the variable nosort is set. The information given is the name of the vector, the length, the type of the vector, and whether it is real or complex data. Additionally, one vector is labeled [scale]. When a command such as plot is given without a vs argument, this scale is used for the X-axis. It is always the first vector in a rawfile, or the first vector defined in a new plot. If you undefine the scale (i.e, let TIME = []), one of the remaining vectors becomes the new scale (which one is unpredictable). You may set the scale to another vector of the plot with the command ** **setscale (17.5.66).
